00:34:54 <arch> my hdd nuked itself: https://i.imgur.com/dZCxK95.png
00:37:45 <arch> electrohead, is it worth keeping the HDD PCBs for repurposing? or does anyone have any fun ideas for reusing a failed HDD?
00:38:42 <electrohead> RIP
00:39:03 <electrohead> I save all PCBs regardless for parts, so that's my answer lol
00:39:10 <steve30> free magnets :)
00:40:01 <rc-garage> take the cover off, and see if you can spin the thing fast enough, that the platters...leave?
00:48:55 <arch> steve30, good idea about the magnets. electrohead i was thinking more like "hacking" the PCB to make it spin faster than 7200rpm rated, maybe 20000 rpm or whatever to see if i can shatter the platters from g forces
00:54:11 <arch> hmm...actually hold on... i think it should be possible to use 2 hacked HDDs to make a reaction control system like spacecraft use. but i guess it really won't be very useful unless it's weightless, suspended, or underwater
00:54:43 <arch> attitude control i mean
00:55:04 <rc-garage> you want to smack it?
00:55:14 <rc-garage> give it a good slap
00:56:27 <arch> lol

01:57:44 <MrMobodies> I think t is worth keeping the PCB
01:58:42 <MrMobodies> in 2023, the barman had this gambling machine with this laser pointer gun where you shoot things
01:59:44 <MrMobodies> the hard disk overheated and he had a reinstall but it was Windows Vista on it and that'd complain about license key and the software he lost key for
01:59:50 <MrMobodies> for the games I mean
02:00:23 <MrMobodies> He had the old hard drive, which was an 80gb Seagate IDE and the PCB looked burn't
02:00:48 <MrMobodies> On ebay for £8 I managed to find that exact same hard drive, similar date, same site code
02:00:58 <MrMobodies> I swapped it over and it worked
02:01:22 <MrMobodies> I copied it over to a solid state as this thing had a sata port in it
02:02:45 <MrMobodies> as soon as the gentleman who sold it untwised the wires going into this gun, that stopped working to and he had difficulty finding a 10 core braided cable so he had to give barman his money back and collected it a month later

03:11:19 <MrMobodies> BBC got this wrong
03:11:24 <MrMobodies> https://www.bbc.co.uk/news/articles/cvg7z7wnq43o
03:11:25 <EEVBot> [url] Virtual tour of former BBC studios in Borehamwood unveiled - BBC News | www.bbc.co.uk
03:11:37 <MrMobodies> This bit: "The BBC Elstree Centre campus first opened as a film studio in 1914, and the other half is home to the BBC's soap opera EastEnders."
03:11:51 <MrMobodies> It isn't it was Neptune Studios.
03:12:31 <MrMobodies> It says so here on another one of their articles: https://www.bbc.com/historyofthebbc/buildings/elstree-studios
03:12:32 <EEVBot> [url] Elstree Studios | www.bbc.com
03:13:45 <MrMobodies> "Hertfordshire were opened in 1914, originally as Neptune Studios" then had many owners until ATV brought them out and sold onto the BBC after the end of their London Weekened Television franchise.
03:14:41 <MrMobodies> How can the BBC get that so wrong despite it being written correctly in one of their older articles
03:19:24 <MrMobodies> It says Neptune House and banks but nothing about the previous owners
03:21:42 <MrMobodies> The author who wrote that article is a very experienced journalist working for the BBC since 2001.

05:16:17 <arch> T3sl4, for https://imgur.com/a/psa-ees-students-M1S0DbI, do you have recommendations for beginner friendly resonant llc controllers?
05:16:39 <T3sl4> lol, lmao even
05:18:06 <arch> :p
05:19:17 <T3sl4> biggest thing i'd say is get comfortable with typical values and what they affect (idle current / loss, magnetics size, load and gain range, etc.), then pick a few controllers and see how they operate
05:20:21 <T3sl4> keep in mind what's scalable; the controller only sees a few volts here or there, it doesn't "know" or care that your inverter is 12 or 1200V, it just needs the signals, levels and timing to be representative
05:21:23 <arch> the reason i was curious is because i have a spare xbox360 psu and it's using resonant llc. it's so light i thought they must have skimped out on capacitors or heatsinks
05:21:28 <T3sl4> hence another introduction: get a eval board, and start scaling parts of it here and there. rewind it for 12 or 24V. rewind it for 200W instead of 100. adjust Lr and C for new pri (Fsw? Vin? Vin range?) variables
05:22:16 <arch> so i was thinking of messing with a smaller build maybe 50w max, 5v in -> 12v out, or something similar
05:22:40 <arch> good idea about eval board actually. think i just might do that. fastest way
05:23:36 <T3sl4> one of the nicest things about em, output filtering is small because load current is supplied nearly continuously from the transformer, and freq/duty (or whatever control variable it's really using) can adjust very quickly (within a cycle, say) to compensate. reaction is fast because Q is low. it's resonant but only barely
05:23:50 <rc-garage> yep, eval is such a legend over here in sweden
05:24:46 <T3sl4> LLC doesn't mean much at low voltages; it shines most at high voltage where Qoss is higher
05:25:32 <T3sl4> for a LV test, you can compensate by using overly large / old MOSFETs, or jamming extra C in parallel, such that the inverter would be rather inefficient hard-switched
05:28:47 <arch> ohh, hmm. ok so i guess it wont be of much use for me as a noob. i dont really feel comfy messing with mains stuff
05:29:40 <T3sl4> as far as "use", probably not, square-pulse converters with <200V FETs are fine, at least unless you need stupendously high density or efficiency
05:29:54 <T3sl4> breadboarding it that way will be the most illustrative tho
05:30:01 <arch> slap on some heatsinks and call it a day :D

15:26:12 <MrMobodies> Like Gianni, he gets caught, he says "I'm sorry", Gianni sacks his whistleblower, and this man "I have a good idea, let's change the rules..", so he's not sorry. I thought staff there had the same level of protection as they do.
15:27:05 <MrMobodies> His wife was working there, so she'd have protection too and I thought security was very high around there.
15:28:29 <MrMobodies> What do you think of that?
15:29:35 <MrMobodies> oh night
